Application led August 18, 1922.

To all whom it may concern Be it known that we, GEORGE E. SnABoYER and PAUL H. ANDERSON, citizens of the United States, residing at Wooster, in the county of lVayne and State of Ohio, have invented a new and useful Method of Constructing Brushes, of which the following is a specification.

Our invention relates to improvements in brushes, and particularly to improvements in method of making paint, varnish, and calcimine brushes and the like, in which the brush material is secured in the brush head by cement or other like adhesive material. The principal obj ect of our invention is to provide a simple and inexpensive and eiicient means of inserting and inlaying the cement material, in softened or semi-liquid condition` between the inner ends of the brush material and ferrule, or head of the brush handle, in such manner as to thoroughly saturate the ends of the bristles with the liquid after they are inserted 1n the ferrule, and surround each bunch of material within the brush head with a larger amount of liquid cement than has heretofore been possible, without permitting any of it to escape into or thru the brush material beyond the ferrule, and to stiffen and make @o more shapely the brush material when assembled in the brush head or block, and better secure the mate-rial therein in the cement drying and hardening process. It consists mainly in providing a novel means for introducing the cement material while in s emiliquid or plastic state, and holding it in compact relation to the brush material during the drying and hardening of the cement, and at the same time preventing its escape to the exterior of the brush, or thru the bunches of bristles beyond the ferrule, thereby making the brush more elastic and durable, and externally free from cement drippings, as hereinafter set forth and stated in the appended claim. y

Our invent-ion is illustrated by the accompanying drawings in which similar letters and figures of reference indicate like parts. Referring thereto, Fig. 1 is a longitudinal sectional view of a brush, showing our completed brush in section; Fig. 2 is a detail rspective View of the ferrule of the brusliedetached; Fig. 3 is a detail perspective view of a perforated plate thru which the bristles D pass into the interior of the ferrule; Fig. 4 is a detail perspective view Serial No. 582,664.

of the cement cup or receptacle, detached from the brush handle and ferrule; Fig. 5 is a like detail View of the cup` with handle attached thereto, and Fig. 6 is a modification of 6o Fic'. 5 for a flat brush.

n the drawings, A indicates the ferrule, which is similar exteriorly to such as are in common use. It may be perforated as at a, in any preferred manner, to receive bunches of bristles or other like brush material, and constructed out of any suitable sheet metal, and the ferrule may terminate at. its lower edge; but in our improved method of construction we place a perforated plate E (Fig. 3) within the lower edge of the ferrule, as shown in Fig. l, of a thickness of about onefourth of an inch, the perforations beingl bored at, a proper slant to give proper shape to the bristles D, when placed therethru; this plate may be covered by the lower surface of the ferrule, in whole or in part, being bored to register with the perforations in the plate, but such covering of the plate is not essential toour method.

The Figs. 4, 5 and 6 show varying forms of a cup` or receptacle, to hold sufiicient quantity of liquid or semi-liquid cement to properly saturate and cover the inner ends of the bristles D, which are introduced thru the perforations of the plate E prior to the application of cement thereto` so as to be perfectly! clean and free from the same until such application, which is made by inserting within the ferrule the cup B enclosing within its thin marginal rim b the said cement; and pressing the cup upwardly, with the bristles D in vertical position until their adjacent inner ends are completely covered and saturated with the cement, so that, by gravo5 ity, thei latter is prevented from passing upwardly thru the perforations of the plate, and thereby also the cement may be detained below the plate E, so as to leave a, space un* occupied therebetween, asshown in Fig. l. 10o After applying the cement in the manner stated, the brush is to be held in vertical position, in a rack or otherwise, until the cement has gone thru a drying and hardening process by heating or otherwise. If prem5 ferred the rim b of the cement receptacle may be attached either to a thin bottom of the cu B, or directly to the block C of the brush iiandle, as may be most convenient for drying the cement; and the brush may be made round, or Hat, or elliptical in form as may be desired for the trade. The cement cup is preferably made. by surrounding the bottom of the cup B, or the block o? the handle G, with a thin metal band of sucient width to hold an adequate quantity of the cement required for the particular brush.

By the means andmethod aforesaid the parts of the brush may be more readily assembled than heretofore, and the quantity of cement for any kind of brush may be measured in advance, and applied without soiling the bristles thereby, and a stronger and more pliable brush constructed than has heretofore been possible with the -use of cement for the urpose.

Having thus what we claim as new and desire to secure by Letters Patent is- The herein described method of construct'- in a brush, comprising inserting bristles or oter brush material thru a perforated plate within a ferrule, and while held in a vertilly described our invention` cal position,'the inner ends of the bristles bein projected` thru said perforations downwar ly sufficient for their immersion in hquid cement, applying the latter thereto by 2 means of a cement cup or receptacle, adeuately filled and pressed upwardly within t e ferrule until said inner ends of brush material are thoroughly saturated and surrounded with the cement, and then, While so 3 held in vertical position to prevent leakage, completing the process by drying and hardemng the cement thus enclosed, substantially as set forth.

In witness whereof, we hereto set our 3 hands this 16th day of June, A. D. 1922, in presence of two witnesses.
